The hardest track was downhill and the problem was the diff clearance it dug in a bit. Soft dirt so no harm but needed a bit of right foot to push it out. As long as someone has a snatchy or winch you'd be fine. I'm very new to I've only been on two trips with my car and only drove this one. Whats your specs and where are you? Can't see on my phone.
Also I live right near here. About 15 mins past pakenham there's twin bp servos at a place called longwarry and labertouche. You turn left there if your going away from Melbourne and to get to the bush you go right at the end of sand road (which comes of princess freeway) onto old highway. First left and then follow that and turn right at forest road. Meeting at bps would be best. Fuel food and heaps of parks there.
